On June 24th the UNIGIS EO4Alps summer school - jointly organized by Z_GIS and GEO - has started. The event is dedicated to the topic “Earth observation and geospatial information: supporting a sustainable use of alpine ecosystems and water resources”. It brings together international students and practitioners from 9 countries and is supported by the European Space Agency (ESA) and the Copernicus Academy. The intense program deals with the key environmental challenges in alpine regions as well as the potential of remote sensing techniques to meet these needs. The combination of international key speakers with hands-on sessions and field trips offers the opportunity to discuss with experts and get first hand experiences. Next week the summer school participants will present their group works in form of posters at the GI_Forum Expo night on Wednesday July 4th.
